ABSTRACT:
A liquid fuel pumping apparatus for supplying fuel to an internal combustion engine has a rotary distributor member in which is mounted a plurality of pumping plungers which are engaged at their outer ends by cam followers which engage the internal surface of a cam ring. The distributor member is axially movable to vary the quantity of fuel supplied. Each follower includes a roller and a shoe and in order to reduce the amount of material required to produce the cam ring, the rollers are of a length substantially equal to the width of the cam ring and are held against axial movement relative to the cam ring. The shoes are held against axial movement relative to the distributor member. The width of the cam ring and the roller are such that the safe Hertzian stress in the cam ring is not exceeded, the additional width of the cam ring to accommodate the movement of the distributor member in previous designs not being required.
